Yes. I buy books with formulas, code (like physics, engineering, programming) in physical form, because the Kindle edition tends to look awful. I only buy the Kindle edition of books that are purely text and/or throwaway (= I won't open it ever again), typically management, self-help books. Also, I buy physical versions of fun books that I read before going to sleep, because I don't want anything digital (= capable of displaying notifications) in my hand when I'm preparing to go to sleep.
